Fast and dirty lens res test

I was selling an old Pentax 300mm lens on eBay a while back. Didn't have any res charts handy. I do have a couple of res charts, but they are buried in storage. So, I used a paper bill instead. Worked out find for eBay.

Looks good at normal magnification, but when you pixel-peep it is just so-so. 

Always go the distance and magnify your tests to get the score. If you really want to test things, shoot a flat bill, engraving only and check the corners.
